Assembly type cavity prefabricated slab of formwork-erecting-free cast-in-situ cavity floor system

Abstract

The invention provides an assembly type cavity prefabricated slab of a formwork-erecting-free cast-in-situ cavity floor system. The assembly type cavity prefabricated slab comprises a reinforced concrete ribbed beam, a reinforced concrete upper flange plate, a reinforced concrete lower flange plate and filler. The reinforced concrete ribbed beam internally comprises at least two longitudinal reinforced concrete ribbed beam bodies and multiple transverse reinforced concrete ribbed beam bodies. The two ends of reinforcements of the longitudinal reinforced concrete ribbed beam bodies are exposed out. Multiple annular reinforcements are arranged on the upper surface of the reinforced concrete ribbed beam. The filler is a polyphenyl block or a plastic cavity or a cement cavity or a slab cavity or an empty net cage. The filler of the assembly type cavity prefabricated slab of the formwork-erecting-free cast-in-situ cavity floor system is exposed out of the upper surface. The assembly type cavity floor slab produced through the process is high in integrity, reasonable in structure, high in quality standard, controlled in procedure and good in self-heat-preservation and self-sound-insulation performance.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to an assembled cavity prefabricated panel technology for a mold-free cast-in-place cavity floor. Background technique [0002] In the 1980s, the production of concrete prefabricated components in my country was in a stage of great development. In the process of housing construction, the country adopted hollow prefabricated slab structures, large slab structures, cast-in-place concrete structures, cast-in-place concrete hollow floor slab structures, and cast-in-place frame shear forces. Wall structure, etc. With the process of housing industrialization, steel-concrete composite structure and steel-concrete composite cavity floor structure system have been developed rapidly. [0003] For example, the ZL98231113.3 concrete thin-walled cylindrical member declared by the applicant is made into a sealed cylindrical filling body, which provides a tubular hollow filling body ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to promote the industrialization process of housing, and improve the existing frame shear wall structure system by using an assembled cavity prefabricated panel of cast-in-place cavity floor without formwork; fully utilizing the advantages of factory industrialization, prefabricated production The prefabricated cavity floor slab solves the problems of construction, environmental protection, weight, cost, and work efficiency in the existing system; the overall force of the building structure is solved by pouring reinforced concrete on site. Concrete is organically combined to optimize the existing frame shear wall structure system technology, transform and upgrade the existing prefabricated frame shear wall structure system, and update it; solve the problems of poor controllability of the overall site pouring in the existing system and implementation technical problems Strong, on-site construction causes environmental pollution, heavy weight, high construction cost, slow progress of the project, and the exemption of a large number of building formwork and steel supports, resulting in long formwork time and affecting the construction speed; the safety hazard caused by the fragile structural parts of steel supports And it is not easy to form industrialized production and other problems
